You're also making an ignorant generalization about my background. I was brought up by a single, disabled mother. We lived below the poverty line for the majority of my childhood. You'd do well to discard your arrogant approach.
On the surface it seems like a reasonable requirement, but it disenfranchises people for little to no return. In-person voter fraud is difficult to do in any meaningful amounts. Estimates show the amount is negligible compared to the kind of disenfranchisement voting restrictions cause.
Additionally there have been a lot of bullshit practices put up to block people from voting: literary test + grandfather clause, poll tax, corporate thugs watching you vote, white supremacists keeping black people out of polling stations, limiting the quantities of polling stations, resisting early voting, using horribly insecure (Windows XP SP1) voting machines, voter records getting purged. Voting is a right, and it's supposed to be the foundation of our democratic republic.
ID costs money, has to be renewed, and is harder to get than it used to be. (Thanks, DHS.) What if you're older, and the building that kept your birth certificate burned down? Or just lost it? This is not uncommon. Do you just not get to vote?
There is no cost to requiring ID... It is you conflating the cost of acquiring an id with the cost of requiring one. As Australia shows, it can be done with a zero cost (birth certificates and Medicare cards are free)
Australia acheives a 90+% voter turn out. (Compulsory voting through fines) even our poorest are able to vote, that remaining 8% who don't vote are overseas, or missing.
US is lucky if it gets to 60%
The US system has serious problems that completely undermine a democracy... But hey, let's forget the forest and focus on this one tree right here.
